4.3.6 Long Term Ageing
The tubing shall be tested in accordance with IEC 60684-2, clause 50, using an oven that meets the
requirements of IEC 60216-4-1 or ASTM D5423, Type 1.
4.3.7 Corrosive Effect
4.3.7.1 Copper Mirror Corrosion
The tubing shall be tested for copper mirror corrosion in accordance with ASTM D 2671, Procedure A, or
IEC 60684-2 clause 33, for 16 hours at 175 ± 3°C (347 ± 5°F). For tubing sizes 1/8 and larger, specimens
shall consist of 1/4 x 1 inch (6 x 25 mm) strips cut longitudinally. Evidence of corrosion shall be the removal
of copper from a mirror, leaving an area of transparency greater than 8 percent of its total area.
4.3.7.2 Corrosion in Contact with Copper
The tubing shall be tested for corrosion in contact with copper for 168 hours at 175 ± 3°C (347 ± 5°F) in
accordance with ASTM D 2671, Procedure B, or IEC 60684-2 clause 32.
4.3.8 Fluid Resistance
Completely immerse three specimens of tubing, prepared and measured in accordance with 4.3.2, in each
listed fluid for 24 ± 2 hours at the temperatures specified in Table 4. The volume of the fluid shall be not less
than 20 times that of the specimens. After immersion, lightly wipe the specimens and air dry for
45 ± 15 minutes at room temperature then test specimens for tensile strength and ultimate elongation in
accordance with 4.3.2.
4.4 REJECTION AND RETEST
Failure of any sample of tubing to conform to any one of the requirements of this specification shall be cause
for rejection of the lot represented. Tubing which has been rejected may be replaced or reworked to correct
the defect and then resubmitted for acceptance. Before resubmitting, full particulars concerning the rejection
and the action taken to correct the defect shall be furnished the inspector.
5. PREPARATION FOR DELIVERY
5.1 PACKAGING
The tubing shall be packaged in accordance with good commercial practice unless otherwise specified.
Individual sizes shall be neatly bundled or boxed.
5.2 MARKING
Each bundle or container of tubing shall be permanently and legibly marked with the size, color, quantity,
manufacturer's identification, specification number and a lot number.
